IMPROVEMENT IN SCRUBBlNG-BRUSHE'S.

The Schedule referred so ln these Letten Patent 'and' making part of the am..

To allwhom it may concern Be it known' that we, RALPH ROCKWELL and ZonA B. CUSTER, of Petroleum Gentle, inthe county of Vcd-ange and State of Pennsylvania, have invented a new and improved scrubbing-Brush; andwve do hercby declare the following to be a full, clear, and exact description of the same, reference-being had to the accompanying drawing makingnI part of this specification, in which- Figure' 1 is a. view in perspective, and

Figure 2 is a sectional elevation. v

I This invention 'relates to the manner of securing the wooden stock of a scrubbing-brush, ortha-t portion in which the bristles are set, vto the base-board, Awitli 'which the bandleis connected, and which bears the rubber strip that operates'as a. drier.

' The invention consists ina wooden stock having beveled edges', in combination with a' base-board havsaid base-board, and extends into a recess formed in the upper side of the stock, and thus prevent-s the latter from moving laterally in the base-board.

Referring to thedrawing- .A is'the base-board;

B, the brush-stock fitted with n. dovetail joint in the base-board l C is the rubber s trip vsecured, in .a groove, having Y either vertical or inclined sides' and running tra-nsvcrsely of the basebald' D is the socket for the brush-handle;

a, the recess inthe base-board; and bthe recess in thebrush-'stck which said socket enters, thereby preventing .lateral displacement of the stock. l

c is the pivot ofthe socket. v

The recesses u and b are of such width as toadmit of inclining the socket eitherto the righe-es shown il the drawing, or to the deft, so as to enable the operator to run either the brush or rubber strip in advunce.

The' function of the brush is, with the aid of water,- to scour floors, and the function of' ythe strip. is to dry them after scouring.

,Having thus' described 'm y invention,

That I claim as new, and desice to secure by -Letters Patent, is

The brush-stock B held inA dovetniled groovesof the 'board A, and prevented from lateral displacement by the socket D entering the recess b, as shown and described.

To the above specification .of our vinvention we have signed our hands this 8th day f October, 1870.
